Abstract
While wave digital filters (WDFs) can always be implemented by commercially available integrated digital signal processors (DSPs), the efficiency of such implementations leaves room for improvement. Modified forms of WDFs are therefore derived that yield DSP implementations much more efficient than those previously available. The approach is particularly suitable for lattice WDFs. The modified WDF-structures can be easily built in such a way that they possess all stability properties desired under signal quantization, thus not only absence of small- and large-scale limit cycles but even e.g. forced-response stability and related properties.
